STEPHEN M. CASEY BY Wmv 7M y ATTORNEYS I5a are imbedded in the wood I5at appropriate points to hold the glass in place, and the adjacentreinforcing edges at the sides and upper and lower ends of the sash areheld together by rivets` I9` which pass through the reinforcing edges I6and also through metal corner strips 2| disposed at the corners of thesash. The sidey reinforcing strips IB arearranged tol fit withinchannelfshaped guide members I 3` which eX- tend vvertically of theframeand provide slide- Ways 22 and 23 for th'ewupper and lower sashes, re'-spectively. It willbe understood that the reinforcing member I.6 andslideways 22 and 23 are: complementary infshape and are dimensioned' sothat the `sash may easily be slid vertically with respect to 'the frame,but, nevertheless, a

48 disposed on the outside of the window which prevents water fromleaking under the frame. The slide mounting members 36 and the top andbottom mounting members 46' and 4l areV held together by slot-and-pinconnections. Thus, a yoke 49 is riveted to the lower mounting member 41as best shown in Fig. '7, saidmember 49 beingslidably received withinthe channelfshapel side mountingwmember 36. An elongated'pinSI passesthrough `apertures in each of the legs" 52 of theyoke-sha'ped member 49and extends through horizontal slots 53 in the lower end ofthe sidemounting member 36. Yoke-shaped member 49, bottom mounting member 41Aand the outwardly-bent flange 50 of frame i3 arev all fixed in positionby rivets 55 substantially Vweather-tight' t isf obtained.

` vVertical guide members I3 are formed substantially `Eshaped in.cross-section as shown par-i" ticularly in Figs. 2, 3 and 4. The uppersash II maybe disposedwithin the channel 22 andthe lower sash I2disposed within the otherchannel of the E-shaped gui'defmember I3. Thus,the upper -and lower sash .maybe individually raised ,orf lowered byhandhwithourl iint'erference one with the other and thereby the degreeof venti lation through the window construction may''be controlled;` e

It lwill`- be understood that ia plurality` of notches k29 may be cutoutof the y"side-guide members I3, said notches receiving spring biasedlatch members .3V-carriedby the reinforcing edges I6 of the sash.This'construction' resembles that shown irl my'P-atent No. 2,288,936.IThe sashr may be held in various positions-of adjustvment by permittingthe latchimembers -3I` to enf gage the notches 29, whereupon the sashwill-be heldin position until the latch" members fare manually retractedby manipulation-ofr nger grips 32 connected to said latches and the sashraised or lowered to' -a new ment.

`The side guide members I3 are receivdwithposition of adjust- 'The'mounting member is heldin the door byv reasonrof4V the fact that theouter longitudinal surface of vathen basel 39 of! the side mountingmember 36l isprovided withk a central longitudinaljrib 56 and-lesser:ribs 51 longitudinally extending along each corner. A conventional doorpanel is held in place by means of a pair of molding strips 58 which:are spaced apart to provide a. gap 59 havingthe .thickness of a woodpanel or a piece of glass which may ordinarily `roccupyfa conventionaldoor panel. The central rib 56 of the mounting member 36 is of athicknessisubstantially equal to the width of said gap 59, i. e., of awood panel or` glass pane and thus, the molding strips 58 hold said rib56- in position as best: shown'in Figs. Zand Il.v The corner ribs I 5`Ibear against said molding'strips 58 and as in the open endsofsubstantially(Lllshaped channel mountingjrrlembers'v 36.r The-distancebetween thev parallel sides 3l ofv the mounting member 36 issubstantially equal to the thickness ofthe side guide memberv I3,butvthe'side guide membersI3 are lsuiciently smaller so fthat they mayslidev within' the mounting membe/rf'3v6 air and watertight. f fSubstantially onelthirdrof the Way below the topand one-third ofthe-way` above the bottom of themounting member 36 is a spring38,"s'u'bn but '.thevt is, close-enough so that the window; is

stantially helical in conguration, one-'end iof.

thespring being xedto the base 39 of mount'- in'g 36' and the other'fendbearing against'the guidev member I3L allV as most clearly shown=inFigs. 3 and 5. `The inner end of spring-38l is xed to base 39=by meansof a rivet 4I passing through the base 39 and having 1a washer'54'2 atits opposite end which `engages one ofthe coils of spring 38.r Theopposite end ofvthesprin'g'38 is free, but bears against the guidemember' I3.

Thus, the spring urges the guide member I3 and mounting member 36apart', but the'force ofthe spring 38 is weak enough so that thev guidemem- `36, thereby compressing the spring 38'.V The top mounting member46k is formed. as a shallow channel extending'across the top oiv thewindow. The bottom mounting memberl'l .ber I3k may be readily slidwithin the channel VWhich'extends acrosspthe bottom of .the windowissubstantially flat with an upwardly bent'Il-ange sistin holding themountinginposition.

l Assuming that'a conventional'door I0 is to be tted vwithV a windowconstruction which is the sub'jvectfvofv the present invention, themolding strips 58 at'the -topfand bottom of the panel are permanentlyremoved. *Molding strips 58 at the sides areV temporarily removed topermit withdrawal of the glass or wood and then replaced. The workmanmanually; rcompresses the' side mounting members 36 toward each other sothat the centralirib 56'ateach side may pass over the high points ofthe'l'molding strips 58"along the sides-ofthe panel. This-compression ismade possible by reason of the r`=fact that the springs 38 compress` andthe 'sfideE guide v,members I3 slide within" the channels which 'make upthe'side mounting members 36; With the central rib 56 in position in gap59 between the molding members 58 thesprings y33 snap the side mountingmembersu36 inposition.' It will be understood that the top mountingmember 46 ts snugly against the topl'of fthe panel opening vand' thatthebottom mountingimember 4'I lits snuglyagainst the bottom ofthepanelwIt will be observed, therefore, that the installation is'simple and requires no special tools or extraordinary skill. I

With the Window in position, as weatherv condi# tions require, thebottom and top half of the sash mayrbe raised Vorlowered toafford therequired degree of'ventilation. Y

If it should be necessary to remove the entire window, as when the dooris being painted or for any other purpose, the upper sash I6 is loweredhalfway and the lower sash I2 is raised halfway so that two sashesoverlie each other. The workman then grasps one of thev side mountingmembers 36 and pulls the same inwardly toward the center of the panel.`This operation compresses the opposite side guide member I3 inwardlyinto the channel of its side mounting member 36. Thereupon the centralrib 56 of the rst side escapes from within the gap 59 between themolding strips 58 which hold it in place and thus the entire window maybe lifted out of the door.

When it is necessary to remove only one sash, as when the pane of glasshas been broken, the two sashes I I and I2 are moved to the-sameposition overlying one another as heretofore described, the sash I2 tobe removed is grasped and moved sidewise, thereby compressing theopposite side guide member I3 into the open channel of the opposite sidemounting member 36. This operation is continued until the reinforcingedge I6 escapes from the channel 23 of the guide member I3, andthereupon the sash I2 may be lifted out but the other sash I I and theentire mounting 36, 46, 41 and guide I3 are left in position.

, The ease and rapidity with which the window may be installed andremoved or an individual sash installed and removed is one of theimportant features of the present invention. This feature has particularutility when the mounting, frame and reinforcement I6 are made ofaluminum inasmuch as it is undesirable to paint such material. The easewith which the sashes II and I2 may be removed from the guide I3 makesit possible to transport the sash to a glazer for replacement of panes.

Although I have described my invention in some detail by wayofillumination for purposes of clarity of understanding, it is understoodthat certain changes and modications may be made therein withoutdeparting from the spirit of the invention or scope of the appendedclaims.

I claim:
